Zero Knowledge

There’s no full-length episode this week, but we wanted to highlighting a new bonus segment available exclusively to zkMesh+ subscribers. In this, we revisit last week’s conversation with Ian Miers, Assistant Professor of Computer Science at the University of Maryland. 

Ian dives deeper into:
The renewed cultural focus on privacy
The evolving narrative around Zcash
His recent research on reducing nullifier state growth without relying on traditional pruning

We return next week with a 6-part series on Lean Ethereum… stay tuned!

In this episode, Anna Rose and Nico Mohnblatt welcome back Ian Miers, Assistant Professor of Computer Science at the University of Maryland, to continue the conversation from a previous episode and dig deeper into his latest work like zk-Promises, zk-Cookies, and Cryptographic Personas. These ZK tools aim to build social networks that protect user privacy while maintaining integrity, like anonymous moderation and reputation systems without central databases. Ian explains how they differ from traditional creds but share ideas around proving attributes securely.

The conversation explores real-world applications, such as banning bad actors without de-anonymizing them, setting rules in private group chats, and creating self-sovereign identities that persist over time. Ian also touches on challenges like stolen accounts, trolling, age checks, and how these primitives could shape future online interactions.

In this episode, Anna Rose catches up with Sean Bowe, a Zcash core developer now leading work on Tachyon, the upcoming Zcash shielded pool upgrade. They discuss the evolution of Zcash’s technical roadmap over the past five years and how it has influenced the design of Tachyon.

Sean then walks through the cryptographic ideas behind Tachyon, including its proving systems, new techniques for pruning nullifiers without disrupting other parts of the protocol, and how the upgrade aims to address Zcash’s remaining scalability bottlenecks. They also explore plans for Zcash governance, wallet UX, and the long-term outlook for privacy-focused zero-knowledge systems.
